LOCK.

Application filed August 12, 1907. Serial No. 388,219.

To all whom it may concern:

Be itknown that 1, CHARLES A. BERRY, of Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Locks; and

I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

adjusted and assembled on a door without disconnecting or altering any of the parts.

A further object is to provide a lock with means for deadlocking the outer knob, and also with antomaticall actuated means bolt and also the dead iocking mechaiiism of the outer knob. With these ends in view my -invention consists in the parts and combinations of parts, and in certain details of construction as will be more fully explained and pointed out in the claims.

In the accompanying drawings Figure 1 is a View in section through a section of the door and inner case of the lock, the section taken in a plane above the knobs thim les. F'g. 2 IS a similar view through the bolt and outer knob, the inner knob being shown in elevation. Fig. 3 is a view in end elevation of the lock applied to the door.- Fig; 4 is a view in section on the line AB of Fig. 2 looking toward theinside knob. Fig. 5 is a view in section of the outer end of the lock showingthe position of the deadlocking slide 12 an dog 19 when the door is standing open. Fig.-6 is a view of the same parts showingtheir positions when the door is closed. igs. 7 and are views of the outside knob and cylinder therein. Figs. 9 and 10 show the means forchanging the adjustment between the key tail piece and dead locking do 19. Fig. 11 is e'view showin the hub and ey tall pieces detached, and Fig. 12 is a view in transverse section looking toward the bolt.

1 represents the inside knob mounted to escntcheon or face plate 3. The knob 1 car: rice the spindle l" which passes through a hole at the inne 1- end of ti-iimble 2 add is held in place, and against displacelnent'by washer 33 hearing against the inner end of thirnble 2, the washer being held in place by pin 34:. The inner end of spindle 1 enters the roll back 7 which with the roll backs 10 and ll are mounted in the inner case 6, the two outer roll backs 7 and 11 having hubs projecting through the case 6. The case (5- is rigidly secured to the outside escutcheon plate 17, by the screws 23 entering threaded holes in the studs 23 integral with plate 17 and projecting therefrom, the studs serving to hold case 6 and its contained mechanism at the proper distance from plate 17.

The front plate 4 is provided with an in wardly rojecting fiange P which latter is secured y Screws to the inner face of outside plate 17. The front plate 4 restsflush with the face edge of the door and is provided atits free end, which is thickened as shown in Figs. 1 and 2, with a slot 49 in' which the flange 48 formed on the front end of the inside plate 3 rests. By means of tl" is flange and slot, an adjustment is provided for to compensate for varyin thickness of doors. The front plate 4 is s otted for the reception of the bolt 5 which latter is hinged at- 37 adjacent to the outside plate 17.

The outside knob 25, which carries the key cylinder, is secured to the outside plate 17, by means of a sprin washer 31'seated in a groove in the kno shank and bearing against a supporting washer 30 restin against the inner face of-plate 17, the kno shank being extended beyond the washer and terminating in a clutch or toothed end 25 which engages or meshes With a. similar shaped end on t 1e roll back 11, so that when outer knob 25 is turned, rollback 11 will move therewith; 3

The cylinder 27 whichrarrics the key 0 lind'er, is secured'to the outer knob 25, by s eeve nut 26, which latter is in turn held in place by not 28. This cylinder27 is passed throu h a hole in the outer face of the knob an its screw threaded inner end enga es the internal threadsin sleeve nut 26. y now rotating nut 26 which may be done by a. special wrench introduced through the inner end of the knob shank, the nut 26 will be screwed onto cylinder 27 thus lock- Specincation of Letters Patent.

Eng the latter in place within the knob. The i oer end of C}l-1l(l(:l' 27 terminates in a hate or llangewlnch latter closes the opt-1r the knob. it is obvious however. that various other means may be employed for preventing the rotation-of cylnit er 2? and hence I do not confine myself to the construction 5 shown for accomplishing this end. 7

"The outside thimble 18 is Pilllllttl'iulltl) secured to plate 17 in the same manner that. thiz'nble is secured to plate 3, nd carries and supports the outer lint 3. 'l he key cylinder whieli rotates in cylinder 97 is provided with a connecting bar 29, shown in 20 Figs. 2 and 7, which extends through a round hole in the hub of roll back 11 and terminates within a slot in the middle rollbaek 10. whereby the latch bolt 5 may be retracted by a ke \i'lien the outer knob dogged as will be. hereinafter described.

From the construction thus far described it will be seen that the inner knob aetuates roll back 7, the outer knob the roll back 11, and the key cylinder in the outer-knob, the roll back 10. Both knobs operate to retract the latch bolt through the medium of a tail niece 8 common to both. This tail piece is U-shape longitudinally, and is slotted at its rear end to embrace the hubs of the roll backs 7 and ll, the free ends of one member of the tail piece being bent outwardly toward the inner knob so as to engage the roll back 7, and the free ends of the other men her bent toward the outer knob and engag- 40 in; the roll back 11.

The front end of tail piece 8 is slotted for the passage of the key tail piece I. the rear end of which is bifurcated to ei'nbrace the roll back 10, and the extreme inner end of tail piece 9 is bent. to engage said roll back. This piece 9 extends forwardly in advance of t'ail piece and is pivotally connei-t'ed Lil Y 19 which as before stated is pii'olall'y mount i ed on the hitch bolt 5 is of hell ('raiik form, the inwardly pr jecting member of which is provided with a hu 15) parallel with the pin 35 on which the (log 1.) mounted.

l 113 is a spring pressed plunger projecting l through flange l ofihe front in a position to engage the stop on the door frame when the door is closed. T liis plunger 16 carries the dead locking slide 12. Whirl) together with plunger 1t; are normally forced outwardly by the spring .14 embracing pin 13 carried by the slide. The slide 12 also earries the guiding pin 44 which moves in a hole in flange \Vhon the door is closed,

; plunger 16 is forced inwardly as shown in ."(J

Fig. 6. thus moving slide 12 up againstand in the path of movement of the lug 19 on the dead locking dog- .lt thus absolutely preventing the bolt 5 from being forced inwardly by an instrument inserted between 95. the strike plate or keeper 46 and the lace plate at of the look.

- 15 and 20 are stop work plunger-s slidingly mounted in the front plate 4 on opposite sides oi the bolt 5. Plunger 15 (as shown in Fig. l) is L-shaped, its inner member 21 being. provided with a slot to reeei e :1 lug on the hub of roll back 11, and the two plungers 15 and 20 are connected by the rocking lever 45. the ends of the latter restlug in recesses in the plungers, so that as one plunger is pushed inwardly the other will be forced out, in a manner similar to -the stop work mt'eehanisni now in general use. When plunger 15 forced inwardly the slot in its inrer member 2''; embraces the lug on the'roll back 11 -1nd thus positively dead looks the outer knob.

In order to prevent the'stop work plungers l5 and 20 from being manipulated by a bent wire or other tool. introduced between the strike plate 46 and the face plate of the door. For the purpose of throwing oil the dead locking mechanism of the roll back for the outer knob have provided the (lead lot-kingslide 1;. (which as before explained to the dead lot-king dog 19 mounted on pin 15.; carried by the hitch bolt Th se tat pieces constitute the latch slide, The tai piece 9 is expanded iininedi:it(-l ll! rear o the front end of tail piece 8 thus l'ormin; shoulders against. which the forward end of th latter ears. 'licii the parts ar in their normal positions as shown in Figs. 1. and (3, these shtnilders rest in comm-t with the front endof tail piece 8, hence when either knob is turned to retract; the bolt. tail piece 5) which is connected to the latch bolt. 60 is retracted by the engag ment of the end j of tail piece 8 with the shoulders on tail l icce 9. When the bolt is retracted by the l l1) roll back 10, through tail piece 9. tail i piece 8 remains passive. Dead locking dogl i l i t l dead locks the bolt 5) with :1 lug 42, which when the plunger It, is forced inwardly by engageuu-in with the top on the door frame, is moved inio a slot ll in stop work plunger 1.3 l!l)\ l1 in 4') and thus dead locks both tt ltllt'tl tl plunger-s 15 and .20 againstmor-ament when the door is closed. This plung r 15 is provided with two slots 41 one at whirh is engaged by the lug 42 when the stop work plunger 15 is in and the other when it is out thus dead-locking the stop work mechanism in its two positions.

The dead locking slide 12, is as shown in Fig. 4. to one side of the plane of movement of the bolt 5 and does not interfere with the free movements of the latter except when His.

tampered with from. the outside as previously explained. When the tail piece 9 is actuated by the turning of any one of the tinned pull on piece 9 then retracts the bolt by the spring 22, en

5. The bolt 5'is yieldingly held in its normal or out. position by the spring 21', which with spring 21 whic yieldingly holds the tailpieoes in their normal positions, is =mounted on iii 38. The stop work plungers are hel against accidental movement agin the shoulder 32 on plunger 15, and the taiIpiece 8 is held in its normal position by the spring 40.

'ith this lock it will be seen that the bolt 5 is dead locked against movement by an instrument introduced between the front and strike plates, and that the deadlockingl mech-- anism of the outer knob, isalso (le: locked when thedoor is closed. It will also be seen, from the construction as above explained, that the lock case 6 carrying the roll backs and tail pieces, together with the outer knob 25 are all carried by the outside plate 17, while the inner plate 3 carries its knob and spindle, hence in order to apply the lock to a door it is simply necessary to cut out a section suiliciently large to accommodate the case 6 and front plate 4, the plates 3 and 17 overlapping and concealing the cut. ihe part-s previously assembled,

and adjusted are placed in their proper po-,

sitions, on opposite sides of the door, the only adjustments necessary being to seat the end of the spindle 1 in its roll back 7 and the flange 48 in roove 49. After the parts have been thus applied, they are secured by screws 53 passing through plate Iiand entering screw threaded sockets in plat 17 and by screws passing through plates 3 and 17 into the door. In locks of this kind. it is customary to extend the front loosely beyond the edge of the inside plate without any councction whatsoever.

By means of the groove 49 and flange 48, I connect the front which is carried bv one plate, to the other plate, thereby providing a much stronger front than in those locks in which there is no such connection.

As shown in Figs. 9 and 10 the throw of the bolt may be adjusted by providing the dog 19 with two holes for the pin 36. By changing the pin from the lower hole as in Fig. 10 to the upper hole as in Fig. 9 and turning tail piece 9 over so as to engage itsroll back 10, I secure a greater throw of the bolt.

Itis evident that many slight changes might be resorted to in the relative arrangementof parts shown and described wit out departing from the Hli and scope of my invention. Hence I would have it anderstood that I do not wish to confine myself to the exact construction of parts shown and described but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of mgfiuvention. i
